The Macurco TX-6-HS is a low voltage, dual relay Hydrogen Sulfide (H2S) detector, controller and transducer.
The TX-6-HS has selectable 4-20 mA output, buzzer and digital display options. It is an electronic detection
system used to measure the concentration of H2S and provide feedback and automatic exhaust fan control
to help reduce H2S concentrations in refineries, pulp and paper mills, waste disposal or other commercial
applications. The TX-6-HS is a low level meter capable of displaying from 0-50 ppm of Hydrogen Sulfide.
Selectable options include:
- Fan relay actuation: selectable from 1 to 20 ppm H2S
- Output: Fan relay, Alarm relay and 4-20mA current loop
- Controls: Digital display (0-50 ppm), buzzer, fan delay, fan minimum runtime
Installation
- Mounts on a standard 4” x 4” electrical box
- 5 A SPDT fan relay controls valves, louvers or exhaust fans
- 0.5 A N.O. or N.C alarm relay connects to warning devices or control panels
- 4-20mA current loop - compatible with the Macurco DVP-120 Control Panel
- Factory calibrated
Other Features
- Supervised system design: detector problem will cause the fan & alarm relay to activate
- Optional calibration kit allows the TX-6-HS to be field tested and calibrated
- ETL Listed to UL 61010-1
Location
A TX-6-HS is normally mounted low in the room on a wall or column one foot above the floor in a central area
where air movement is generally good. Use the same spacing as for smoke detectors, 30-foot centers, 900 square
feet per detector (465 sq. meters). The coverage depends on air movement within the room or facility. Extra
detectors may be needed near any areas where people work or where the air is stagnant. The TX-6-HS mounts
on a 4x4 electrical box supplied by the contractor. Do not install the TX-6-HS inside another box unless it has good
air flow through it. Do NOT mount the TX-6-HS where the normal ambient temperature is below below 0°F or
exceeds 125°F (below -18°C or above 52°C).
